Description

Technical Field

[0001] This utility model relates to the field of shaft construction technology, and in particular to a hoisting device for shaft construction. Background Technology

[0002] A suspended platform is a load-bearing platform used for vertical lifting and transportation, widely used in construction, shaft operations, mining, and other fields, primarily for transporting personnel, tools, equipment, or building materials. A suspended platform typically consists of a load-bearing platform, lifting lugs, a wire rope connection structure, and safety devices such as anti-tilt and anti-fall devices. It works in conjunction with a lifting device (such as a winch or crane) to achieve vertical movement within shafts or building facades. The suspended platform structure must possess sufficient strength and stability to ensure the safety of personnel and materials during load changes and operation. This device effectively improves work efficiency and is particularly suitable for working environments with limited space where it is inconvenient to arrange large lifting equipment.

[0003] In existing vertical shaft construction, winches are typically used in conjunction with wire rope hoists or cages to vertically transport personnel and materials. However, in actual operation, existing vertical shaft hoisting devices lack guiding, limiting, and collision buffer mechanisms at the contact points between the hoisting platform and the hoisting frame. This makes it difficult to maintain stability of the platform's center of gravity during lifting, leading to lateral swaying, impacts, or tilting within the shaft. This can cause equipment wear, structural fatigue, and even safety accidents. Therefore, these systems present certain safety hazards and limitations in their use.

[0004] Based on this, we propose a hoisting device for shaft construction to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a hoisting platform device for vertical shaft construction, which can solve the problem that existing vertical shaft hoisting platforms lack guiding, limiting and buffering mechanisms during the lifting process, resulting in lateral swinging, impact and deflection of the hoisting platform, causing equipment wear, structural fatigue and safety hazards.

[0007] To solve the above-mentioned technical problems, this utility model provides a hoisting device for vertical shaft construction, which adopts the following technical solution: it includes a hoisting derrick, and a construction hoisting device is provided at the bottom of the hoisting derrick. The construction hoisting device includes a supporting top cover, and a lifting controller is installed at the bottom of the supporting top cover. The construction hoisting device is hoisted at the bottom of the lifting controller. The lifting controller includes an electrical control box, and a guide cover is installed at the bottom of the electrical control box. Two sets of winch protective covers are connected to the bottom of the guide cover.

[0008] The electrical control box has two sets of steel cable winches connected in the middle. The steel cable winches are matched with the winch protective cover structure, and the inside of both sets of steel cable winches is wound with hoisting steel cables.

[0009] Optionally, the construction hoisting platform component includes a construction hoisting cage, with metal hoisting platforms installed at both ends of the construction hoisting cage, and a hoisting connector connected to the top of the construction hoisting cage.

[0010] Optionally, two sets of telescopic connecting rods are installed on both sides of the top of the hoisting connector. A steel cable fixing device is installed on the top of each set of telescopic connecting rods, and a compression spring is sleeved and connected to the middle of each set of telescopic connecting rods.

[0011] Optionally, the outer sides of the two sets of metal hanging plates are provided with several sets of circumferentially distributed telescopic adjustment grooves. Guide blocks are installed inside the telescopic adjustment grooves. The guide blocks are matched with the structure of the telescopic adjustment grooves. A spring shock absorber is connected between the guide blocks and the telescopic adjustment grooves. A guide roller is also provided at one end of the guide block.

[0012] Optionally, the bottom of the hoisting derrick is connected to several sets of metal columns, and the inner side of each set of metal columns is provided with a guide groove.

[0013] Optionally, the guide groove is matched with the guide block structure, and the guide groove and the guide roller are in rolling contact.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The vertical shaft hoisting platform device designed in this scheme, by adding a telescopic connecting rod, a cable fixing device, and a compression spring between the construction hoisting platform component and the hoisting steel cable, can stably connect two hoisting steel cables to the top of the construction hoisting platform component. It can realize auxiliary functions such as buffering and shock absorption, load self-adaptation, and directional steady state. During the hoisting platform lifting process, the telescopic connecting rod can adjust its extension and retraction within a certain range according to the force conditions. Combined with the elasticity of the compression spring, it can effectively absorb and disperse impact energy, reduce the sway amplitude of the hoisting platform, and avoid local overload. This improves the operational stability, anti-interference ability, and safety of the construction hoisting platform component during the lifting process, and effectively avoids structural damage and safety hazards caused by hoisting platform swing, tilting, or impact.

[0016] 2. The vertical shaft hoisting platform device designed in this scheme, through the ingenious cooperation between the metal hoisting platforms installed at both ends of the construction cage and the metal columns, guide chutes, and other structures, can achieve stable control of the hoisting platform during operation inside the vertical shaft. The guide chutes and guide blocks adopt a matching and interlocking structure, and achieve rolling contact with the guide rollers, so that the hoisting derrick can provide effective guidance and limiting support around the construction hoisting platform components in the lifting state. The spring shock absorbers installed inside the telescopic adjustment groove can provide good buffering and energy absorption effects when the hoisting platform is subjected to force changes or external impacts, preventing problems such as swaying, tilting, or local collisions caused by the shift of the hoisting platform's center of gravity. This effectively improves the stability, safety, and reliability of the device during vertical shaft construction, ensuring smooth operation of the overall structure and greater protection for personnel.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Refer to Figures 1 to 7This utility model provides an embodiment of a hoisting device for vertical shaft construction, including a hoisting frame 1. A construction hoisting assembly 2 is installed at the bottom of the hoisting frame 1. The construction hoisting assembly 2 includes a supporting top cover 3. A lifting controller 4 is installed at the bottom of the supporting top cover 3. A construction hoisting component 5 is hoisted at the bottom of the lifting controller 4. The lifting controller 4 includes an electrical control box 6. A guide cover 7 is installed at the bottom of the electrical control box 6. Two sets of winch protective covers 8 are connected to the bottom of the guide cover 7. A transmission connection is made in the middle of the electrical control box 6. Two sets of cable winches 9 are structurally matched with the winch protective cover 8. Both sets of cable winches 9 have hoisting cables 10 wound inside. This vertical shaft hoisting device, through the coordinated use of the electrical control box 6, guide cover 7, and winch protective cover 8, can prevent the two hoisting cables 10 from tangling during the hoisting and lifting of the construction hoisting platform component 2. It also provides auxiliary functions such as buffering and shock absorption, load self-adaptation, and directional stability for the two hoisting cables 10 during winding and adjustment, thus improving the lifting and lowering of the construction hoisting platform component 5. The system ensures operational stability, anti-interference capabilities, and safety, effectively preventing structural damage and safety hazards caused by the swinging, tilting, or impact of the construction hoisting platform component 5. The construction hoisting platform component 5 includes a construction cage 11, with metal hoisting plates 12 installed at both ends. A hoisting connector 13 is also connected to the top of the construction cage 11. Through the hoisting connector 13 installed on the top of the construction cage 11, two hoisting steel cables 10 can be connected and fixed to the middle of the top of the construction cage 11. The top of the hoisting connector 13 has... Two sets of telescopic connecting rods 14 are installed, and steel cable fixing devices 15 are installed on the top of each set of telescopic connecting rods 14. Compression springs 16 are also sleeved and connected in the middle of each set of telescopic connecting rods 14. By adding telescopic connecting rods 14, steel cable fixing devices 15 and compression springs 16 to the top of the top of the hoisting connector 13, the two hoisting steel cables 10 can be connected and fixed to the top of the construction hoisting platform component 5. This can provide auxiliary functions such as buffering and shock absorption, load self-adaptation and guiding stability for the two hoisting steel cables 10 that are wound and adjusted.

[0028] The outer side of the metal hoisting platform 12 is provided with several sets of circumferentially arranged telescopic adjustment grooves 17. Guide blocks 18 are installed inside the telescopic adjustment grooves 17. The guide blocks 18 are structurally matched with the telescopic adjustment grooves 17. Spring shock absorbers 19 are connected between the guide blocks 18 and the telescopic adjustment grooves 17. One end of the guide blocks 18 is also provided with guide rollers 20. By installing spring shock absorbers 19 inside the telescopic adjustment grooves 17, a good buffering and energy absorption effect can be provided under the force change of the hoisting platform or the action of external impact, so as to avoid problems such as swaying, tilting or local collision caused by the center of gravity shift of the construction hoisting platform during operation. The bottom of the hoisting derrick 1 is connected to several sets of metal columns 21. Guide grooves 22 are respectively opened on the inner side of the several sets of metal columns 21. The guide groove 22 opened on the inner side of the metal column 21 can provide guidance and limiting support for the construction platform component 5 that is raised and lowered inside the hoisting derrick 1. The guide groove 22 is structurally matched with the guide block 18, and there is rolling contact between the guide groove 22 and the guide roller 20. Through the structural design of matching the guide groove 22 with the guide block 18 and the rolling contact between the guide groove 22 and the guide roller 20, it can be ensured that the construction platform component 5 is vertically guided along a predetermined trajectory when it is raised and lowered inside the shaft, preventing it from tilting, deviating or swinging. In addition, the low-friction rolling contact between the guide roller 20 and the guide groove 22 can effectively reduce running resistance and structural wear, making the lifting of the platform more stable and efficient.

[0029] Working Principle: The vertical shaft hoisting device designed in this scheme mainly consists of a hoisting frame 1 and a construction hoisting platform assembly 2. The construction hoisting platform assembly 2 includes a supporting top cover 3, a lifting controller 4, and construction hoisting platform components 5. The lifting controller 4 works in conjunction with the electrical control box 6, guide cover plate 7, and winch protective cover 8. Because the structure of the steel cable winch 9 and the winch protective cover 8 are matched, it can guide and limit the hoisting steel cable 10 inside the steel cable winch 9 for winding and adjusting, which can prevent the two hoisting steel cables 10 from getting tangled during the hoisting and lifting of the construction hoisting platform assembly 2. In the case of winding, by adding telescopic connecting rods 14, steel cable fixing devices 15 and compression springs 16 to the top of the lifting connector 13 on both sides, the two lifting steel cables 10 can be connected and fixed to the top of the construction platform component 5. At the same time, they can also provide auxiliary functions such as buffering and shock absorption, load self-adaptation and guiding stability for the two lifting steel cables 10 during winding and adjustment. This improves the operational stability, anti-interference ability and safety of the construction platform component 5 during the lifting process, and effectively avoids structural damage and safety hazards caused by the swinging, tilting or impact of the construction platform component 5.

[0030] The vertical shaft hoisting device designed in this scheme uses metal hoisting platforms 12 installed at both ends of the construction cage 11. These metal hoisting platforms 12 work in conjunction with structures such as the metal column 21 and guide chute 22 through the cooperation of telescopic adjustment groove 17, guide block 18, spring shock absorber 19, and guide roller 20. The guide chute 22 and guide block 18 adopt a matching and interlocking structure, and achieve rolling contact through the guide roller 20. This allows the hoisting frame 1 to provide effective guidance and limiting support around the construction hoisting platform component 5 in the lifting state, enabling stable control of the hoisting platform during operation inside the vertical shaft. The spring shock absorber 19 installed inside the telescopic adjustment groove 17 provides good buffering and energy absorption effect under the force change of the hoisting platform or external impact, avoiding problems such as swaying, tilting, or local collisions caused by the center of gravity shift during operation. This effectively improves the stability, safety, and reliability of the device during vertical shaft construction, ensuring smooth operation of the overall structure and greater protection for personnel.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
